The WL2863D is a linear regulator capable of supplying 250-mA output current. Designed to meet the requirements of RF and analog circuits, the WL2863D device provides low noise, high PSRR, low quiescent current and very good load /line transients.

The device is designed to work with a 1 μF input and 1 μF output ceramic capacitor (no separate noise Operation bypass capacitor is required).

The WL2863D regulators are available in standard DFN1x1-4L Package. Standard products are Pb-free and Halogen-free.
